Cumberbatch was speaking after the first screening of the new BBC1 drama The Child in Time, in which he stars.
Cumberbatch said actors could not afford to be snooty about what work they took on.
There is now such a blur between film and TV that if any actor remains snobbish about the small-screen medium, “it is their loss”, Benedict Cumberbatch has said.
The fact Cumberbatch is such a huge celebrity meant filming on a London street presented its own issues.
